SNMP is frequently used to monitor systems for fault conditions such as temperature violations, hard drive and fan failures, and voltage fault conditions. The iDRAC generates events that result in Simple Network Management Protocol (SNMP) traps and entries in the iDRAC Lifecycle Log.

The iDRAC generates events in response to changes in the status of sensors and other monitored parameters. When an event with predefined characteristics occurs on your system, the SNMP subagent sends information about the event, along with trap variables, to the management console.

Each event generates an identifier called the trap ID and a list of trap variables that provide additional details about the event. The traps of the iDRAC MIB are organized into five subgroups of traps. Each subgroup corresponds to one of the following five categories of events that iDRAC supports:
